CHAIN.

Specification of Letters Patent.

Application filed. April 7, 1916. Serial No. 89,589.

To all whom it may concern Be it known that I, EDWARD A. MOORE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Chains, of which the following is a specification.

My invention relates to an attachment or accessory for use with various kinds of chains among which are Waldemar chains. This type of chain stretches between opposite vest pockets, and is not provided with any center bar or any center piece or tripod, and has no means for securing the chain at any point intermediate its length; its only engagement being at its ends with a watch and pencil, knife, or other article.

The essential objects of my invention are to furnish an intermediate guide and support for the chain; to insure the chain and its connected article against theft or accidental escape; to permit the use of the chain as adouble chain; to enable the wearer to utilize the entire length of the chain by detachment whereby a maximum of freedom is afforded for manipulating the knife, pencil or other article connected therewith; to afford a means of chain support adapted to facile, universal, and secure engagement with the clothing of the wearer; to permit instantaneous engagement and disengagement of the chain, and without removing the device from the garment, and to attain these ends in a simple and inexpensive structure.

To the above ends essentially my invention consists in such parts and combinations of parts as fall within the scope of the appended claims. a

In the accompanying drawings which form a part of this specification, Figure 1 is a front elevation of a chain in engagement with the support attached to a vest, Fig. 2, an enlarged front elevation of the support, Fig. 3, a section of the same on line 3-3 of Fig. 1, and Fig. i, a rear elevation of the same.

Like reference characters indicate like parts throughout the views.

In the drawings 6 are the button holes, 7 the buttons, and 8 and 9 the opposite pockets of a vest 10.

11 is the attaching ring of a knife, pencil, or other article in the pocket 8; and

13, the suspension ring of a watch 14: in the pocket 9.

A vest chain 16 provided with end rings or swlvels 17 and 18 is shown engaged with the rings 11 and 13 respectively. Loosely engaging this chain is an attachment, guide, or support represented in a general manner by the numeral 20. This member comprises parallel front and back plates 21 and 22 respectively connected at their ends by a hook 23, the whole forming a U-shaped frame. To the lower or free end of the plate 21 is a resilient arm 24: extending below the plane of the walls as at 25 where the arm has an open loop or vertically dis posed. bend 26 and thence extends upwardly in front of the plate 21, and is then curved inwardly and downwardly as at 28 until it isadjacent to or'in contact with the plate 21, as at 29. In the present instance there is-a space 30 between the arm and the front plate at this point. Thence the arm ex tends downwardly and outwardly, as at 31 completing a circular hook upon the upper end of the arm 24.. At the junction of the front plate and the arm is preferably an external shoulder 32.

Soldered or otherwise fixed in the frame in the present instance is a lining plate 33 having surface prong or prongs 34: on one portion, and an opening 35 in its opposite portion. The wall 22 has also an opening 36 at this point to accommodate a cam 37 which cooperates with the prong or prongs 3 1-, when any prong is present. Integral withthe cam is a lever arm 38 pivoted by lateral pins 39 in seats 4-0 in the plate 22. The lever arm is vertical in the opening 36 when the parts are in closed or clamping position as shown in Fig. 3. but is manually oscillated rearwardly and downwardly to bring the cam out of engagement with any fabric between the prongs and cam.

The member 20 is inserted into a button hole 6 with the plates 21 and 22 against the front and back surfaces of the vest respectively, and with the yoke resting upon the fabric forming the bottom edge of the but ton hole. In this position the frame is clamped by manipulating the lever 38.

The chain 16 rests in the loop 26 of the arm 24 and is of greater diameter than the passage 30, so that it will not accidentally escape therethrough. When, however, it is plate.

desired to disengage the chain from the re taining device, as for enabling a free use of the .knife or pencil, the chain is manually elevated by raising the knife from the pocket 8 and this movement brings the chain into contact with the "curved guiding surface 31 of the hook and forces the resilient arm 24 outwardly, permitting the escape of the chain through the passage 30. To reengage the chain it is downwardly pressed against the curved surface 28 which guides it through the passage3O into its original or engaged position.

When it is desired to convert the chain into a double chain, the ring or swivell? is disengaged from the ring 11 and that end of the chain is folded back and attached to the ring 13.

1. Ina device of the character described, a frame comprising a yoke, a front plate, and a back plate, andan arm upon the lower portion of the front plate extending out- I wardly and upwardly adapted to embrace a chain and terminating adjacent the front 2. In a device of the character described, a frame comprising a yoke, a front plate, anda back plate, an upright resilient arm upon the end of the front plate provided with an arcuate bend adjacent its connection with the front plate and adapted to engage a chain, and a curved guiding member upon the free end of the arm adjacent an intermediate portion of the front plate.

3. In adevice of the character described,

a, frame comprising a yoke, a front plate,

and a back plate, a resilient arm upon the free end of the front plate extending downwardly, outwardly and upwardly adapted to embrace a chain, and a circular hook upon the free end of the arm spaced from an intermediate portion of the plate a less distance than the thickness of the chain.

4. As an improved article of manufacture a safety attachment for chains, comprising a frontplate, a back plate, a yoke connecting the plates at one end, a clamping member in one of the plates, a resilient arm integral with the free end of the front plate pro vided with a loop extending belowthe plane of the front plate, and a hook upon the free end of the arm adjacent an intermediate portion of the front plate.

5. A safety attachment for chains, comprising a back plate and a front plate with oppositely disposed bends and a free arm extending from the bend of the front plate with its free end curved inwardly toward the front plate and formed into a curved hook.

6. A safety attachment for chains, comprising a back plate and a front plate with oppositely disposed bends and a free arm extending from the bend of the front plate with its free end curved inwardly toward the front plate and formed into a curved hook, and means pivoted in the back plate and operable between the back and front plates to clamp a fabric therebetween.

In testimony whereof I have affixed my signature.

EDWARD A. MOORE.
